No, yaySIM does not provide an unlimited data eSIM plan for DR Congo. All of the plans listed for that destination are fixed data plans with a hard limit of 20GB. Examples include the CD_20_30 and GL-120_20_30 bundles, which give 20GB for 30 days, as well as the GL-139_20_90 and GL-120_20_90 options that provide the same 20GB allowance for 90 days. Choosing a fixed data plan can be more cost‑effective for most travelers unless they require significantly higher data usage.
